FAQ for CDO and Net4j

General

How can I enable tracing?

If running as Eclipse launch config it's easy: just turn on tracing on the tracing page of the launch config (plus all net4j and cdo plugins in the list).

If running standalone:

    OMPlatform.INSTANCE.addLogHandler(PrintLogHandler.CONSOLE);
    OMPlatform.INSTANCE.addTraceHandler(PrintTraceHandler.CONSOLE);
    OMPlatform.INSTANCE.setDebugging(true);

CDO

What's the best way to convert an XMIResource to a CDOResource?

You just need to copy/move the root objects over to the CDOResource. There's a good example in ImportResourceAction.doRun():

Invalid language.

You need to specify a language like this: <source lang="html4strict">...</source>
